Reflux and vomiting

[JazzMan]

My 12wk old DS is suffering from reflux and not keeping milk down. He was born 6wks early.

He has been constantly sick (projectile) after nearly every feed for over a month and moans/cries a lot after being sick.
I feel like we havent had much support from our dr or the paediatrician who said it will go by the time he is 6mths.
The baby gaviscon didnt help, we have tried changing milks (cow and gate as well as a supermarket own) and he eats sat up and stays up right for as long as possible after.

I am wearing thin. I hate seeing him like this. Personally I think it's something more but they won't listen.

Any hints or tips that may help?

My son suffered from reflux as a baby and now my dd does too although in a much milder form. Have you tried swapping over to cow and gate anti reflux milk I think apatamil also do a version it's a thicker formula and for us as helped with the reflux from the first feed we used it. We only get the odd bit of spitting up now.
